I played the games out of order so I’ll do it in the order I played the games since that did influence my choices.
DA:I- My first DA game, first romance was Josephine romanced by 2-handed warrior Mace Trevelyan
DA:O- First romance was Leliana. I wanted to romance her in Inquisition but sadly couldn’t, so she was my first choice in Origins and until recently, my favourite romance in the series (ironically it’s now Morrigan)
DA:2- Merril was first, what can I say? She’s cute and I prefer having Varric in my party over Isabella, though I did still enjoy Isabella’s, especially since my Hawke who romanced her was humorous, resulting in some brilliant quips
